T0 all whom t may concer/fi Be it known that I, JAMES CQHENRY, a`

citizen of the United States,"andfa resident of East St. Louis, county of St. Glair,y Statel of Illinois, lia-ve invented certain new and useful Improvements in Carbureters, ofk

which the following is a speciiicatioii.'

The main 'object ofmyfinveiition is tov provide an improved construction of carbureter in which the oil is more completely vaporized and mixed and intermingled with` the air than heretofore has been possibleso that an increased efficiency is eected. v

A further' object of myinvention is to provide a carbureter having .an atoniizing -'chamber or passage-way which istapering 1 showing a portion of the Y auxiliary fuel feeding m'eansl'forlftliecar-k tapering direction.

' In order that my invention"` ymay readily comprehendedand understood, reference maybe had to the accompanying drawings in which I have ,illust-ratedeer-v in one direction ffioni the point atwliicli f the mixture of fuel and air are deliveredr thereto and which widens and flaresfoutwardly in a direction at right'angles to' the Other objects and advantages of my iiivention will be pointed out inthe detailed description thereof which follows or ywill be apparent from such descriptioiiy "e more tain forms of construction embodying the same but it should be understood .thatY changes in thedetails of construction claims be made within the scopegof the without departing therefrom.A

A

The passage-way 8 is connected with the float chamber 16 by means of a passage-way 15. The float. chamber 16 is of known type and is supplied with liquid hydrocarbon kfrom the kfuel tank (not shown) through i leverv 291.

bined with the weight of the outer end porthe passage-way 17 which passage-way is controlled by means of a `valve 19 which in turn is controlled, by means of a float 18 and the pivoted radially situated levers 2().

It `will be understood that when the float chamber 16 is empty or substantially so, the float 18 rests upon the outer ends of the The weight of the float comtion ofthe levers20a is sufficient to cause the inner endsof said levers to lift the said valve 19 out of engagement with its seat at the inner end of the passage-way 17. Vhen this occurs the fuel flows through the said passageway 17 intoi the chamber 16 and Vcauses upward movement of the float 18.'

Such upward movement removes the weight of thesaid float from the levers 20a. When this occurs' the valve 19 actuated by gravity assisted-.by the spring 19a returns to closed position as illustrated in Fig. 1 0f the drawi ings.

Supported between the upper section 2 and thelower section 1 of the body portion of the carbureter iS a centrally arranged rotatable spindle 20 Ahaving an axial opening or bore therethrough, through which the valve member 11 extends. `21 designates a circular member, shown in Figs., 2 and 3, which member is carried upon l andffixedly secured to the upwardly extend- Vingpiojection 6a. 'n The lower end of the spindle 20 yrests upon the member 21 and upon the horizontal wall 23 of an annular Y member, designated as a whole by the ref- 'erenceV number 22, which is secured to the and lower edge portions, as indicated iny Figsl and2 of the drawings. The purpose of these perforations is to permit the passageof air into the mixing chamber to be hereinafter described. The'vertical wall 24 is also provided with a third row orseries f of perforations 30 which are situated intermediate the upper Aand lower rows of perforations 25.

The horizontal wall 23 of the member 22 is also provided with a plurality of air openings 26 asshown in Fig. 3.

The member 22, as illustrated, may be removed and another member substituted therefor, changing the air and fuel openings therein as desired.

r1`he member 21 is provided with a central passage 27 of greater diameter than the valve member 11 from which extends a plurality of passage-ways 28, as shown in Fig. 2 of the drawings.

Nozzles 29 are secured in these passageways 28, the outer ends of which nozzles are situated in alinement with and in proximity to the respective perforations 30. The liquid fuel is discharged from the nozzles 29 into the perforations 30 and byreason of its power of adhesion a greater or less portion thereof adheres to the edges of said perforations. e

By reason of the simultaneous forcing of air through the perforations 30 it will be understood that a spray is formed consisting of a mixture of air and the hydrocarbon. In other words, the fuel is atomized.

31 designates an annular, removable and interchangeable valve which is secured to the rotatable spindle 2O a short distance from its lower end. The lower edge of the said annular valve is situated in a plane substantially coincident with the lower edge of the vertical wall 2-1 of the annular member 22. VThe annular valve 31 is provided with a plurality of circular openings 32 and a plurality of oblong openings 33 said openings'being of different lengths.

The respective groups of openings are arranged in rows peripherally of the Said valve. The series of openings 32 are separated from the openings 33 vby an intermediate solid or unbroken portion 35. The purpose of making the openings 33 of different lengths is to provide means whereby the openings 25 and 30 in the vertical wall 24 of the annular member 22 may be successively opened or closed.

The valve 31 is operated synchronously with and automatically as the butterfly valve 6 is operated by means which will be hereinafter referred to and described.

Located within the section l of the body of the carbureter is a member, which may in a sense be regarded as a baffle, comprising a downwardly extending circular portion 36 which is situated at the central top portion of the section 1, surrounding an intermediate reduced portion of thev member 20,v a horizontally extending portion 37, a downwardly extending annular portion 3S, and an inwardly and downwardly inclined extending portion 39, all of said parts being integrally connected. The circular opening formed at the center of the downwardly and inwardlyv inclined portion 39 receives the lower edge of the rotatable valve 31 and assists in holding the same in proper position. Y y v y f l lt will be observed that the space between the downwardly inclinednortion39 and the` inner upper surface of the` bottomwall of the section lis wedge shapedin cross section.

. A second member, which also in a sense may be regarded as a baffle, is also pro-` vided, said member beingvsituated interiorly of the member comprising the angularly related parts36, 37, 33 andv Thesaid sec-L ond member comprises an inner annular portion l which surrounds and engages the corresponding annular portion 36, aphorizontally extending annular portion 42a depending annularfi portion 43, anda horizontal angular portion 411i-, said-portions being integrally connected with each other. The lower end of thepart or portion l1-'projects aconsiderable distance below the lower edge of theannular part 36. The annular *por` tion 1.4iisl provided with an opening lthrough said' ope* ogt the sa which enters therein throughfthe openings Such airl passesA around the outerxr edge of the said baile plate andthen'ce igor-w wardly underneathfkthe same` and tn 1leei space immediately above ther-annular memthrough the Aopenings 32 into` the an ber22. From the latter space the air passes through the Aopenings rQinto the annularv 01 vand j ein also chamber between the depending wall the periphery ofthe membery 2l. enters the annular space Awithin ythe, depending wall 24 'from .the space` .outsideiof the member 36, 3'4"', 3S, IThe airisadapted to passk 'from the saidr annular space through the openingsQ and30 and through kthe openings 33 into the mixingjchamber, .be-y tween `the said membersormefd of the'parts 36, 3'?, etc. and 41,42, etc.V The passage of air throughvthe openings 3Q vacts upon'the oilwhich has issuedffrom the. nozzles 25% to atomize and vaporize the same.[ rA spray is produced which mixes and ,interininglesJA with the air whichpasses through the open- Y ingscf on opposite'sides of theopeningsjBO.

it willloe observed that they portion otthe mixing chamber or passage-way betweenthe parts 39 and lll isV wedge-shapedv in 'cross' section and tapers Vfrom toward the center outwardly, but ywidens or flares 1n; a, d1rection at v`rightangles to the.;.taperingdirec-r reter chamber:y i,

tion.` yThe extent ofthe taper is 'such that the-capacityof thejchamberat kall transverse points is the same. The result is that a more p ke'liicient and complete intermingling and va* porization-is effected than if the .mixing 'Y chamber or passageway were `of equal trans verse thickness or width throughout. The

vaporous" fuel passes from the wedge-shaped portion lofthechamberr upwardly into the annular space rbetWl-en the parts 38 ,and 143 and thence KLinto ythe ktransversely arranged relatively ywide space betweenthej'parts37v n and'fQ,l andthence through the opening in the topfpart37 :into they outletpassage 5 whencel it travels to the engine, due to they suction of the latter in kknown manner. The capacityfof Lthe annular spacev between the parts 38-and 43'V is equalltovthe capacity of the,v portion of the mixing chamber space between the parts 39 andlll.

The passageo theair and'liquidl fuell `through the openings in thedepending wall 24 is controlled by the annular valve 31 which f issecured toand moveslwithfthey member 20. The member 20 is operated simultane- '90 yously ,with and automatically as thebutter- .l fiy valve@ is operated, asheretofore stateflr In order, to operatethevalve` 6 therod 5l /isrotatedby means of a throttle lever (not shown) valve is supported bythe rod i515 Depending from thefsaid rod 51-isk an air-m63 connected at its lower endwith afglink 50 -whichfinturn isconnected to an arm ,'54 rhaving connection,with;4 aA sleeve y5K5.

In view of the fact that the air which is drawn through the inlet port 3 in the carbureter is heated the chambers outside of the member 36, 37, 38, 39 and with the member 41, 42, 43, 44 may be regarded and termed as thermal chambers, since they contain heated air, the heat of which is transmitted by conduction to the mixed air and fuel within the fuel mixing chamber. It will be seen that the construction as described` provides for and includes a mixing chamber of such shape and arrangement that the atomized liquid fuel is thoroughly mixed with the air and is completely vaporized to produce an explosive vapor of a character such that all of it is utilized in the engine so that there is a minimum loss of power and efficiency. f

I have also shown'means for introducing into the outlet passage or chamber 5 of the carbureter either an inflammable gas or high test inflammable liquid fuel, used in case of an emergency when the carbureter is not operating satisfactorily, as Vwhen it is cold and it is desired to start the engine, or water which may be introduced and which acts as an aid to the low test fluid fuel. The said device comprises a three-way valve'cock 61 which is connected by means of a tubular member 62 to the section 2 whiclrtubular member extends into the interior thereof terminating in the outlet passage 5. inner end of the saidV tube is flattened out and corrugated as indicated at 63 in said Fig. 7, such corrugations dividing the exit into a plurality of flaring perforated pas sage-ways 63.

G0 Aand 60 designate intake plugs having connection by means of the three-way cock and the passage-way through members 62 and 63 into the outlet chamber 5. The negative pressure in said chamber 5 is regulated by the throttle valve 6 during the operation of thecarbureter. The intake plug is adapted to be connected with an inflammable gas supply rtank through an adjustable, constant, pressure reducing valve of known type (not shown) while the intake plug 60 is adapted t0 beconnected with a water supply tank through a float chamber or other' constant level Vdevice (not shown) from Y which the water is drawn `which is introduced into the outlet passage 5. The supply of either liquid fuel orwater is influenced by the throttle, opening and closing thereof respectively increasing and decreas ing the amount used.

In the modified form of construction,

shown in Figs. 8 to 11, embodying myin-.

vention, the sections 1 and 2 are connected together in any suitable manner and the air The is supplied through the inlet opening 3. The opening into an auxiliary air chamber is controlled by means of a valve 4 supported upon the rod 4a. By adjusting the nut at the outer end of said rod 4a the vtension 'of the spring 4f is varied so as to vary the force necessary to depress the valve 4. The upper end of the central member or spindle 4 is reduced as indicated at 3 and is supported in a blind hole or socket in the upper wall of the section 2. The lower end portion of the member 4 is reduced as indicated at 5 so that an annular chamber surrounding the said reduced portion may be formed by the annular valve 15. The lower or bottom wall of the section 1 ofthe carbureter is provided with an extension havingV a passage-way 1l therethrough, said passage-Way connecting a fuel supply tank (not shown) through a float chamber (not shown) with the passage-way 11 for the supplying of liquid fuel to the carbureter. The lower end of the said passage-way 11 terminates in a cock 10 for the same purpose as described in connection with the cock 10 shown in Fig. 1. The inner side of the bottom wall of section 1 is provided with a recess 8 in which the passage-way 11 terminates.

A. cap 9 is seated within the said recess said cap being provided with a boss upon its lower side which rests upon the central portion of the said recess. The outer edge portions ofthe said cap 9 are spaced from the bottom of the said recess so that an annular ,-hamber is formed between the outer edges of said cap and the bottom of said recess. The cap is secured in position by means of .screw 10. The upper side of the cap is provided with a boss or projection which extends into a recess formed in the lowerV end of the member 4. By reason of the formation of the reduced portion 5 upon the member' 4 a flange 6 is formed at the lower end thereof which flange is seated upon the cap 9', its edge being in alinement with the edge of the said cap. The cap 9 is provided in its lower side and at its center with a shallow recess from which extend a plurality, three being shown. of radiating passage-ways 9a best shown in'Fig. 10 of theY drawings. The outer ends of these passageways communicate with the annular chamber surrounding the boss upon the lower side of the cap 9. A plurality ofradiating passage-ways 12 are also formed in the bottom wall of section l of the carbureter chamber, said radiating passage-ways being best shown in Fig. l0 of the drawings. outer ends of these passage-ways commumcate with the upright tubular members 13 constituting liquid fuel discharge nozzles the upper ends of which terminate in the mixing chamber of the carbureter.` Said The v ends are in alinement substantially withV Vthe l holes 20 formed in the outer ring 52 of an vnular rings 52 v annular member which consists of three 4rings 52, 52 and 52 secured together. The openings 20 are considerably wider in a direction Iparallel with the rings -than the holes 20 which are tormedin the inner anof the said annular member. The openings 20, however, are of greater length vertically considered than the openings 20 so that the capacity of the two openings are respectively substantially the saine. The areas ot' the respective holes 20 in the ring 52 should be equal to or greater than that kof the respective holes 20 and 20 and their width or height transversely of the ring 52 should be equal to the length of the holes 20 while in a direction parallel with the said vring they should be of a width equal to or greater than the holes 20. rhe annular valve l5 is supported upon the rotatable member 4, said rotatable.member being rotated by means of the sleeve 55 in.

the same manner as described in connection with the constructionshown in Figs. 1 to 7 y' inclusive.

The lower edge of the annular valve 15 is seated within an annular groove formedV passage-ways' are successively opened by reason of the presence of the openings 16.

The member consisting of the parts 36, 37, 38, and 39 is substantially the same in construction as the member which includes the saine parts in the construction shown in Figs. 1 to 7 inclusive. The member comprising the parts 41, 42, 43, and 44 is substantially the same in construction as the member including the correspondingly numbered parts shown in Fig. 1 of the drawings, the

only difference being that in the modified construction the said member is provided with an auxiliary air inlet opening at 41 which is closed by means of the valve 4.

The inner edge of the parts 39 and 44 terminate in contact with and support the annular member comprising the rings 5 2, 52 and 52. The tubular passage-ways 13 project through `openings'formed at intervals in the edge of the said part 39.

Extending diagonally of the chamber within the parts 41, 42, etc., is an annular plate 42 which divides the said chamber into two annular chambersV as is apparent from Fig. 8 of the drawings. The said inclined annular member 42 is provided withv a plurality of openings 43 which are adapt` ings in the valve member 44 are of differentk ktion. 5 of vthe member 4.

andl graduating ylengths similar to the openvalve 44 is rotated.v

Also situated ywithin the chamber Informed Aby the parts 41, 42, etc., and below the annular platey 42 is aftruncated cone-shaped baiie plate 46 the outer edge ofr whichfis situated adjacent to the upriglitpart r`lliel portion of the yheated air which passes lfrom the inlet 3 into the annular space in- .side of the part 3G passes through openings 45 into the space below the inclined annular plate 42 V`and Athence raround the outer edge lot the baille .plate 46 underneath the saine .and through `openings 19- intothe annular `-chamber surrounding the reduced portion .jo Athe member ^4. kWhen the annular valve 44 is rotated, (which occurs ywhen the member 4 with rthemember 4 is rotated to f ymove the valve 15" to open it) so as to open kthe openings r43 kand the 'vacuum created in the chamber of the carbureter'by the suction of the engine is such kthat the excess of pressure of the atmosphere upon the out side of the valve 4 .over the ypressure of the `air uponfthe inside, said valve 4 is opened to permit airto enter the auxiliary air cham`r ber.V above the inclined annular plate 42. It then passes .through the openings 43 and lthrough tubular connections47 kto .the portion ot' the mixing chamber intermediate the `parts 39 and 44..`

The heated air which enters the kinlet 3 and travels downwardly upon theoutside of `rthe ypart 38 passes forwardly 'underneath the part .39 around the tubular membeis13 andthroughthe -openings 17 into the annularchamber surrounding the reduced poi'- n This air, as well as that which Ahas entered through the openings 19vb`efore kdescribed is `permitted, to

pass, when the valve 15 is open, through' the graduated openings '18 through the openings 20, 20 and 20". As'the air issues `from the openings 20` some of it strikes against the edge of the openings at` the Lipper ends of the tubular members 13 and facts upon any liquid fuelwhich may bepresentupon the said edges ,to vaporize the same. y

The liquid` fuel is dischargedy trom the Vupper yends of the tubular members 13, is

absorbed and atomized 'by' the air as yit rescapes from the opening or' openings 20.

Under certain conditionsof operatiomas ",4 by the return stroke or strokes of the piston of the engine cylinders is not sufficient to ki f allow'th'e excess of pressure of the atmos-` n.

` pliere upon the outside of the valve to overcome `the resistance of the krspring 4f and cause downward movement of said valve to open it. Under certain other conditions of operation, however, as when the engine is operating at its highest capacity and when greater quantities of liquid fuel are introduced into the Vvaporizing chamber when consequently a greater quantity of air is necessary toy furnish the proper proportion of air to the liquid fuel supplied to the mixing chamber, the said valve is opened so that an auxiliary supply of air` is produced. When the valve 4, in the form of construction shown in Fig. l, does not open the air supply for the carbureter enters through the holes 4e and 4b and, in the construction shown in Fig. 8 of the drawings, the air passes to the mixing chamber through the holes 45 and through the annular chamber between the parts 38, 39 and the wall of the section 1 of the carbureter body.

It not only may but probably would be the case that the valve 4 would remain closed and would be opened under conditions other than those presupposed above, such conditions as presupposed being merely taken by way of example.

The construction is such, as already indicated, that the capacity of the mixing chamber, not only that portion of it which occupies the space between the parts 39 and 44 but also that portion thereof which occupies the space between the parts 39 and 43, is the p same capacity at all points.

By my invention the liquid fuel and the air are so thoroughly intermixed and intermingled that the said fuel is completely va- 'porized so that the mixture acts with a maximum of eiciency without any loss of power whichY might be due to improper vaporization.

It may be noted that the valve 15 is shown in Fig. 9 in the position it occupies when the butteriy valve 6 is in closed position. As the throttle'lever (not shown) is operated to open the valve 6, the valve l5 is turned to the right so that the openings 20 are successively opened as described. The capacity of the carbureter is thus increased by using more of the atomizing chamber and diminished by using less of said chamber.
